A method for determining behavior of a viscoelastic material at a first temperature includes performing five or more measurements of a dynamic parameter as a function of deformation at each of at least a second, third, and fourth temperature. Eleven or more data points are chosen from the measurements. Each data point comprises a value of the dynamic parameter, an associated deformation, and an associated temperature. Values of the eleven parameters are determined by inserting at least eleven of the data points into a first equation. The first temperature and the values of the eleven parameters are inserted into the first equation. The dynamic parameter is approximated as a function of the deformation at the first temperature using the first equation. A related apparatus is also disclosed.
